+# DevExpress VCL Reports—Generate a PDF Report Using a non-GUI application
+
+This command line application uses the DevExpress VCL Reports components to generate a PDF report.
+The application obtains data from a database using a SQL query that includes report layout parameters.
+
+The example includes projects for both [Delphi](./Delphi) and [C++Builder](./CPB).
+
+> ![Example of a PDF report produced by the command line application, showing an alphabetical list of products](./images/report.png)
+
+## Prerequisites
+
+-   Microsoft Windows 10 or newer
+-   Embarcadero RAD Studio IDE 12.3 (Athens) or newer (Community Edition is not supported)
+-   [Northwind sample database for SQL Server](https://learn.microsoft.com/en-us/dotnet/framework/data/adonet/sql/linq/downloading-sample-databases) as a data source for the report
+-   DevExpress VCL Components v25.2.3 or newer
+
+## Implementation Details
+
+By following the steps outlined in this example, you'll create a standalone command line application using the
+[DevExpress VCL ](https://docs.devexpress.com/VCL/405469/ExpressReports/vcl-reports).
+
+
+### Prepare a Template Report Layout
+
+An application needs a template report layout, created in the [Report Designer](https://docs.devexpress.com/VCL/405469/ExpressReports/vcl-reports).
+You can [store a report layout in a `.repx` file](https://github.com/DevExpress-Examples/vcl-reports-store-layout-template-file)
+or [in a database](https://github.com/DevExpress-Examples/vcl-reports-store-layout-template-database).
+
+This example loads a report layout from the [`Layout.repx`](./Layout.repx) file.
+
+### 
+
+## Documentation and Examples
+
+-   [Documentation: DevExpress VCL Reports](https://docs.devexpress.com/VCL/405469/ExpressReports/vcl-reports)
+-   [Example: Store Report Layouts within Text Files](https://github.com/DevExpress-Examples/vcl-reports-store-layout-template-file)
+-   [Example: Store Report Layouts in a Database](https://github.com/DevExpress-Examples/vcl-reports-store-layout-template-database)
+
+## Files to Review
+
+-   [`PDFReportGenerator.ini`](./PDFReportGenerator.ini) defines configuration settings used to generate a report.
+    In your product, you can implement these settings as 
+-   [`Layout.repx`](./Layout.repx) contains visual report layout and database connection data.
+-   [`Delphi/PDFReportGenerator.dpr`](./Delphi/PDFReportGenerator.dpr) generates a report in headless (non-GUI) mode.
